Abstract :
To estimate the localization of RFID tag in an open room, we use AOA method instead of RSSI. In this paper, we take an advantage of the certain angle coverage of UHF RFID, and design a set to make UHF RFID reader whirl around an axis to scan each tag that can be found with the constant angular rate, so that the locations of tags are obtained by the two sets according to their time-of-difference and angle.
